Re: 140 A.I.R. exhaust manifolds

My engine block is apparently an AIR, of course it has none of the trappings. Is there any meaningful difference in an AIR or non-AIR engine block?

Meaningful?
I would have to say, no.

After I tune I will repost. I think first order of business is distributor advance curve. Would carbs benefit from rejetting? Lastly manifolds.

The only differences the A.I.R engines have are the pistons and heads of the 95 and 110 hp engines, plus the carbs, distributor, and exhaust manifolds. Otherwise, no mechanical differences.

Incidentally, I later rebuilt my 140, and was able to verify that there was no mechanical difference in it from a non-smog 140. So the only thing that I can conclude is that the smog equipment strangles the engine above 2500 RPM. I've also had other owners tell me that their experiences were the same.
